Functions of the CompTrol Interface expansion module
5.1.3 Resistive circuit
If a fixed temperature setpoint is to be transferred to the indoor units, two fixed resistors or two
potentiometers can be connected to analog inputs
X3-S
+
X3-(+RV)
and
X3-S
+
X3-(-RV)
to act
as voltage dividers. A temperature setpoint between 18 °C and 30 °C can be specified.
Resistive circuit operation for analog input is possible in the following programs:
–
Program 0 and programs 2 to 7.
